The NHS40 main switch is a high-performance and reliable load isolator switch for industrial applications. With a current capacity of up to 40 A and high switching power, it is ideal for demanding use cases. Part of the H200 product line and H233 series, it is designed as a 3-pole on/off switch for front panel installation. Its robust construction features a long black handle, a chrome-plated bezel, and a stainless steel mounting plate. The NHS40 is highly resistant to dust, water, and high-pressure cleaning, thanks to its IP67 and IP69 protection ratings. With a mechanical lifespan of at least 100,000 cycles and versatile mounting options, it is a durable and flexible solution.
